Real World Applied PowerShell

Webcast: Real World Applied PowerShell

If you missed this week’s live webcast, well, you’re in luck! We have a recording available as well as some of the scripts used in this webcast for your copy+paste pleasure.

Clearing Event Logs

# This will clear a single log
Clear-EventLog -Log Application, System
# This will clear all the logs
Get-EventLog -List | Foreach-Object {Clear-EventLog -Log $_.Log}

Note: The Get-EventLog cmdlet only grabs the classic Event Log logs. If you need to view all the windows logs, including the more modern logs in modern OSes, you may wish to use the Get-WinEvent cmdlet.
To see the difference, compare:

Get-EventLog -List

with

GetWinEvent -ListLog *

DISM

Enable-WindowsOptionalFeature -Online -FeatureName TelnetClient
